Title: Viscosity controlled hydraulic pump
Inventor: KABEI NOBUYUKI
IPC: F04C13/00
Filed: 1988-08-06
Abstract: PURPOSE:To orient a system total unit to a high pressure and to increase conversion efficiency of energy by using magnetic fluid for working fluid in an oil hydraulic pump to suitably control viscosity by the action of magnetic force. CONSTITUTION:The first gear 201 mounts to its teeth 211 of multiple quantity each permanent magnet 401 so as to place its S pole in the outside. While the second gear 202 mounts to its teeth 212 of multiple quantity each permanent magnet 402 so as to place its N pole in the outside. Thus, a magnetic field 500 is formed between the gears 201, 202 and a housing 301. Now, when magnetic fluid is used for this gear pump, pump efficiency is improved by increasing viscosity in case of an operating pressure being increased. While a gap part between the teeth 211, 212 and the housing 301 increases larger, so that magnetic flux density in the periphery of each permanent magnet 401, 402 decreases, and a bed influence by an increase of the viscosity can be almost neglected.

Title: Magnetizing apparatus for brushless motor
Inventor: FUKUSHIMA SHINJI
IPC: H02K15/03
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetizing apparatus by which a magnetic-pole part for drive and a magnetic-pole part for frequency generation can be magnetized nearly simultaneously and by which the magnetization accuracy of a magnet rotor is enhanced, by a method wherein respective magnetization yokes at the magnetic-pole part for drive and the magnetic-pole part for frequency generation are electrified nearly simultaneously and the magnet rotor is magnetized. SOLUTION: A winding 10 of a magnetization yoke 7 in a magnetic-pole part 4 for frequency generation is arranged so as to be separated from the end face of a magnet rotor 1. An annular magnetic pole 8 is arranged so as to be close to a magnetization yoke 6 in a magnetic-pole part 3 for drive without a distance from the magnetization yoke 7 for frequency generation. Then, the magnet rotor 1 is placed, and the magnetization yoke 6 for drive and the magnetization yoke 7 for frequency generation are electrified simultaneously. Thereby, both a magnetic flux which is generated at a time when the magnetization yoke 6 for drive is electrified and a magnetic flux which is generated at a time when the magnetization yoke 7 for frequency generation is electrified are converged with reference to a yoke in the magnet rotor 1 and to the annular magnetic pole 8.  As a result, magnetization man-hours can be reduced, and an irregularity in the magnetization of the magnet rotor can be eliminated.

Title: Control signal generating circuit
Inventor: MATSUURA TORU
IPC: H04L27/38
Filed: 1989-07-27
Abstract: PURPOSE:To obtain a control signal of a stable transversal filter with comparatively simple circuit constitution by inputting an error signal and a clock signal whose period is T through a gate so as to inhibit a latter half bit of the error signal. CONSTITUTION:Outputs of shift register circuit 103, 104 receiving error signals EP, EQ are inputted to one of two inputs of AND circuits 135, 136 and a clock signal CLK(T) whose period is T is inputted to the other input of two inputs of the AND circuits 135, 136. Thus, the AND circuits 135, 136 inhibit an output of a later half T/2sec of the outputs of the shift register circuits 103, 104 and output an L level. Quadrant discrimination signals DPO, DQO of the output of EX-OR 111-119 (or EX-NOR 120-122) are outputted as the area in a timing of latter half T/2sec because error signals EPO, EP+ or -1, EQO, FQ+ or -1 are fixed to logical L in the latter half T/2sec in each input signal. Thus, a transversal filter is stably controlled with comparatively simple circuit constitution.

Title: Photodetecting device
Inventor: NANUN YUZO
IPC: G01J9/00
Filed: 1984-09-18
Abstract: PURPOSE:To easily detect light with unknown wavelength in a short time by splitting measured light to two optical paths, detecting the quantity of light from one optical path and the transmission wavelength peak of the light from the other optical path, and measuring and displaying both. CONSTITUTION:Light from an optical fiber 2 is made incident on a switching means 4. The switching means 4 moves up and down a mirror 6 which is slanted by, for example, 45 deg. periodically through a displacing mechanism 8 to split the light to the two optical paths. Then, the light of one optical path is inputted to, for example, an Si photodiode 10, etc., to detect the quantity of the light. Further, the light of the other optical path is made incident on a wavelength dispersing element 12 such as a plane diffraction grating. Then, the light dispersed according to the wavelength is incident on a position detecting element 14 to detect the wavelength. Then, the quantity of light detected by the photodetecting element 14 is corrected automatically with the wavelength obtained by the position detecting element 14. Therefore, the quantity of light is corrected automatically with the wavelength, so the light having unknown wavelength is easily detected.

Title: Selective calling radio communication system
Inventor: KASUGAI TERUAKI
IPC: H04Q7/20
Filed: 1982-11-10
Abstract: PURPOSE:To attain sure selective calling from a calling station to a called station by adopting simple constitution. CONSTITUTION:A preset dial 7 of a device of the calling station presets a selective calling code of a device of the station to be called. In depressing a press switch 10, a logical controller 6 drives a transmitter 2 and a modulated transmission output is transmitted to an antenna 1 by using an encoded selective calling signal obtained from a coder 4. When this transmission is finished, the logical controller 6 switches the antenna 1 to a receiver side 3 to bring the mode to the reception waiting mode for a prescribed time. The cycle of transmission and reception is repeated by the number of times predetermined by the control of the logical controller 6. All mobile stations receive the transmitted radio wave during this time, discriminate whether or not the signal correponds to the own station, and when one of the mobile stations confirms at least twice that the signal is addressed to the own station, the station operates an incoming notice tone generator 13 by using the logical controller 6.
